• FFMPEG sendcmd command limitation

  18 novembre 2022, par Stahlauge

  i try to draw text into a video with drawtext and sendcmd.
In the sendcmd file there are over 9100 commands defined (each frame needs a different text).
All my commands are build this way.

  


  0 Parsed_drawtext_1 reinit 'text=\102030GA01, 102040Ap05
von oben, in Fließrichtung
[0,00]   17.11.2022 10\:22\:04:fontsize=28.928569157918293:y=5:x=0:fontcolor=#FFFFFF';
0.04 Parsed_drawtext_1 reinit 'text=\102030GA01, 102040Ap05

  My command is.

  


  ffmpeg.exe -y -i "17112022_102204.mp4" -vf "sendcmd=f=drawtextcommands.cmd,drawtext=fontfile='Ubuntu-L.ttf':text=:fontcolor=black@1.0:line_spacing=5, drawtext=fontfile='Ubuntu-L.ttf':text=:fontcolor=yellow@1.0:line_spacing=5,drawtext=fontfile='Ubuntu-L.ttf':text=:fontcolor=yellow@1.0:line_spacing=5,drawtext=fontfile='Ubuntu-L.ttf':text=:fontcolor=green@1.0:line_spacing=5" -c:v mpeg4 -qscale:v 5 -f mp4 "102030GA01_2022-11-17_10-21.mp4"


  


  My ffmpeg Version is n5.0.4 lgpl.
If i run this command with the sendcmd file on my develop laptop it works just fine (i7-10850H and 32GB RAM) but if i run the excat same on a Surface (i5-1035G4 and 8GB RAM) or Dell Latitude 5175 (Intel m5-6Y57 and 8GB RAM) i get an error

  


  [Parsed_sendcmd_0 @ 000002454188c540] No Targed specified in interval #XXXX, command #0 


  


  where XXXX is different each time i run it. All PC runs Win 10.

  


  I can´t really find the problem why i get this error on the tablets but not on my Laptop.
Maybe it´s a hardware ressource problem even FFMEG doesn´t have any requirements at all ?

  


  I only can get it to run on the tablets if i delete lots of commands from the sendcmd file.
I can´t define excatly the amount i need to delete because each run i can have more or less commands that are working.
But i can say i need to delete a lot more commands on the Dell tablet then on the Surface on to get it to run.

  Ah j’avais pas vu la notif, faudrait que je suive ce projet :)

  Bonne idée et d’accord avec le cahier des charges.
  La 1ère série retenue a l’air bien, simples et flat, mais pas trop : Papirus, Numix, Vimix
  Pas de préférence particulière pour l’une ou l’autre.

• Diference between pkt_duration and pkt_duration_time in ffprobe

  16 décembre 2016, par albertoiNET

  When I execute next ffprobe command in an HLS stream with parameter to show frames in specific stream video in flat format and grep with ’pkt’ pattern, it returns this info :

  $ ffprobe -i http://xxxxxxxxxxxxxxxx/PCMDY_SUB.m3u8 -show_frames -select_streams v:0 -print_format flat | grep pkt
  
  ...
  
  frames.frame.229.pkt_pts=2438664735,
  
  frames.frame.229.pkt_pts_time=27096.274833,
  
  frames.frame.229.pkt_dts=2438664735,
  
  frames.frame.229.pkt_dts_time=27096.274833,
  
  frames.frame.229.pkt_duration=3600,
  
  frames.frame.229.pkt_duration_time="0.040000",
  
  frames.frame.229.pkt_pos=13348,
  
  frames.frame.229.pkt_size=2510,
  
  
  
  frames.frame.230.pkt_pts=2438668335,
  
  frames.frame.230.pkt_pts_time=27096.314833,
  
  frames.frame.230.pkt_dts=2438668335,
  
  frames.frame.230.pkt_dts_time=27096.314833,  
  
  frames.frame.230.pkt_duration=3600,
  
  frames.frame.230.pkt_duration_time="0.040000",
  
  frames.frame.230.pkt_pos=15980,
  
  frames.frame.230.pkt_size=2389,
  
  ...

  What is the difference between info with _time pattern and without it ?.

  I supposed that pkt_duration are in microseconds, and pkt_duration_time is in seconds. It’s true ?
